    Rodent or packing materials in there could have supplied the "fuel". If the engine were running properly, and the catalysts working as intended, there would normally not be enough fuel downstream of the cats to cause an explosion. If there was an air leak in the installation, alternative fuel source and super heated gas coming from the cat - BOOM!

    First off! The Roush mid-resonator catback exhaust was designed to be used with the stock catted mid-pipe in place. Therefore, I don't buy in for a single moment about the resonators being mounted just before the rear axle as a contributing factor for causing catalytic converters to overheat. If that were in fact the case? there would be far more wide spread complaints rather than just a few isolated issues. Actually, up until the OP posted his recent experience, I don't recall coming across any other posts regarding an exhaust system component exploding from a catalytic converter overheating due from installing mid-mounted resonators lol. Another reason I don't buy into your claim, is prior to the debut of the S197 Mustang in mid 2004, the exhaust systems were all designed with the mufflers mounted before the rear axle. Perhaps it's possible the OP's issues were related from an improperly calibrated tune, but that's also highly doubtful, as installing a mid-muffler/resonator cat-back exhaust does not require any additional tune modifications. That being said, I stand by the previous post regarding the OP's issue was more than likely caused by either a manufacturers defect or possibly from some form of road construction debris :shrug:

    Also note that all factory exhaust systems for the Coyote 5.0 cars include resonators!

    I'm guessing that there was never any damage and it was just something melted onto the outside...

    I'm guessing that system is no where near new. Several rust spots around that "blowout". This thing was rotten when he bought it.

    My bet here is that he bought a second hand exhaust that someone had stored with some plastic bags shoved inside to keep critters and stuff out. Installed without removing the bags. Bags melted...blew a bubble... the bubble popped.
